OPERATION DURING A POWER FAILURE
The 5810XTR2 valve/controller includes integral power backup. In the event of power failure,
the control shifts into a power-saving mode. The display and motor shut down, but it
continues to keep track of the time and day for a minimum of 48 hours.
The system configuration settings are stored in a non-volatile memory and are stored
indefinitely with or without line power. The Time of Day flashes when there has been a
power failure. Press any button to stop the Time of Day from flashing.
If power fails while the unit is in backwash, the control will save the current valve position
before it shuts down. When power is restored, the control will resume the backwash cycle
from the point where power failed. Note that if power fails during a backwash cycle, the
valve will remain in its current position until power is restored.
The control will not start a new backwash cycle without power. If the valve misses a
scheduled backwash due to a power failure, it will queue a backwash. Once power is
restored, the control will initiate a backwash cycle the next time that the Time of Day equals
the programmed backwash time. Typically, this means that the valve will backwash one day
after it was originally scheduled.
